ed to be suspended from the ce1 ng of the room to be cooled-and ventilated and provided with lateral air .dischar orts through which streams ffresh' coo air will be directed into the room.

A further object of the invention is the provision of a cooling and ventilatin system of the character stated wherein t e air distributing pipe shall be equipped with means by which any nunuberofthe .air`\dis v charge ports may be closed or partly -closed so as to enable the air to be distributed about ythe room in the manner best calculated to p-roduce the most effective results. A still further object ofthe invention is the provision of a cooling and Ventilatin system of the character stated which sha1 `be simple and durable, which may be readily secured in place in the room-to be cooled.

and ventilated, and which may be maintained in operation at acomparatively low cost.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of arts hereinafter fully described and claimed, and illustrated in the accompanying drawings, wherein:

Figure 1 is a horizontal sectional view illustrating the application of my improved cooling and Ventilating system,

Figure 2 is a vertical sectional view illustrating the manner'in which the air `distributing pipe of the system is suspended from the ceiling 'of the room to bevcooled and ventilated,

Figure 3 is a detail vertical sectional view taken on the plane indicated bythe line- 3-3 of Figure 1,

igure 5 is a detail sectional view taken on the vertical plane indicated by the line 5-5 of Figure Figure 6 is a detail sectional view taken on the vertical plane indicated by the line 6 6 of Figure v.Figure 7 is a detail view showing the manner in which the air discharge ports and air deiiectors are formed, and

Figure 8 is a sectional view taken on the plane indicated by the line 8-8 of Figure 7.

In the drawings, 1 designates the walls, 2 the ceiling, and 3 and 44 the doors of a room' of a building, one of the outer walls of which is designated 5. The cooling and Ventilating system.l comprises an endless air other `suitable formation,

tangular or ary apted to be arranged in the and which is a .room to be cooled and ventilated in the manner suggested in Figures 1 and 2. *The pipe -comprises a plurality of sections .7 which are connected together by couplings 8. The ends of the pipe sections 7 are received in the couplings 8 and are secured therein by cap screws 9. The pipe 6 is suspended from ythe ceiling 2 of the room-by hangers 10.

The upper ends of the hangers 10 are secured 1n brackets llwhich are in turn secured to the ceiling 2, and the lower ends certain of the couplings'S.

The pipe sections 7 are each provided in their lateral sides with longitudinally extending rows of air discharge ports 13. A casing 14 is secured to the inner side of each pipe section 7 over each row of air discharge ports 13 therein. These casings 14 are provided with .elongated slots 15 which nestablish communication between the interior of the pipe sections 7 and the discharge ports 13. Valve plates 16 through the methereof are secured in sockets 12 carried by dium of which the slots 15 may be either w fully Vor partly closed to control the volume of air discharging through the ports 13 are pivotally mounted within the casings 14.v Pins 18 are employedtopivotally mount the valve plates 16, and they extend through the casings 14 and centrally through the valve plates 16. When the valve plates' 16 are in fully closed position they are -arranged in overlapping contact with each other, and when they are in partly or fully opened position their outer portions 4extend into the pipe sections 7 'in themanner i1- lustrated in Figures 4 and 5. The .valve plates 16 of each casing 14 are pivotally connected at their inner ends as at 19 toa rod 20. Control screws' 21 which have threaded engagement with the pipe sections 7, are connected to the rods 20 by pins 22 carried by the controlv screws and slots 23 in the rods. The pipe sections 7 are provided with threaded bosses 24 for the re- `distributing pipe 6, which may be of recception of the control screws 21. The connection between the valve plates 16 and the control screws 21 is such that'when the control screws are turned inwardly the valve plates will be moved into closed'position,

and such that when the control screws are turned outwardly the valve plates will be moved into opened position. When the valve plates 16 are in partly or ullyppened 24. The control screw sections 21and 21h are swivelly connected as shown at 21 in 'order to prevent any turning strain on the ments.

inner sections 21IlL and their connection with the. rods 20 when the outer sections 21" are turned to adjust the valve plates 16.

An outwardly flaring iiue 22 extends from one end of the air distributing pipe 6 to the outer wall 5 of the building, and' it is provided at its outer end with aflange 23 to permit it to be secured to this wall by bolts 24 or other suitable fastening ele- To establish communication between the flue 22 and the outside atmosphere, the wall 5 is provided with an opening 25, and to force air through the flue 22 into the distributin pipe 6 an electric fan 26 is mounted in t e outer end of the flue. At the inner end of the flue within the air distributing pipe 6 is positioned a spreader 27 which divides'the air discharging from the flue 22 into the distributin pipe 6 so as to cause the air to trave through all branches. of the distributin pipe 6.

The air discharge ports 13 are formed by partly strikin lup portions of the pipe sections 7,.and t ese ortions 28 are bent inwardly and arrange at such an angle as tocause the air striking them to be delected through the discharge ports.

From the foregoing description, takenv inconnection with the accompanying draw-4 ings,'it'should be apparent that the current" ual streams o ischarge ports 13 .of each pipe section into the room. Shouldv it be f ound desirable to cause morev air to be'dlschaiged from any one or more of the ipe sections 7 than from the remainder of t e pipe sections this may be done byfully or artly.closing the valve platesA 16 of the ot er sections through the medium of the screws 21. v

It should be understood that the drawings are merely illustrative and do not retend to give exact proportions. Furt ermore, the said drawings are illustrative of a preferred construction it being my expectation that various changes and modiiications may'l be made without departing from the'spirit and scope of the invention.

'What is claimed is: v 1. A cooling and Ventilating system including a distributing pipe provided with a series of discharge ports, a casing located within the ipe over the discharge ports and provide with a slot establishing comthe same partl orA air municatioii betweenthe interior thereof and the ipe, and means associated with said slot or controlling the amount of air entering the casing, said means comprising pivoted valve plates, a rod connecting the valve plates, a member pivotally connected to the rod, and a bolt threaded in the pipe and loosely connected to the member.

2. A cooling and Ventilating stem including a distributing pipe provided with a series of discharge ports, a delector located within the pipe adjacent each discharge port, a casing located within the pipe over the discharge portsA and deilectors and provided with a slot establishing communication between the interior thereof and the pipe, and means associated with said slot for controlling the amount of air enterin the'4 casing.
